2012 Camaro v6 with e39 comp installed in a jet boat modified factory harness when trying to read efi can identify computer read info and start to read about 17 seconds in it does a reset and says error cant read data
tried only standard and alt keys only both read serial num and lock on to read starts to read then quits
feel im missing something is there something different on obd2 plug wiring for e39 have done current updates
